and

3 Claims.

This invention relates to a device for mounting photos, picture cards, etc. on album sheets and the like. These devices, in the form of corner pockets or pieces, generally consist of paper 5 or paper-like material, transparent as well, and

are stamped, folded and pasted of this material in different cutting dies and in wholesale manufacture the work is done by the aid of machines. In the manufacture of the known device of this character much trouble has been experienced in applying the adhesive, which is done either before, during or after dressing the corners, by which, due to the necessary paste charging means and drying devices, an unsatisfactory produce often results. By the present invention, any additional application of any paste layer to the material serving for stamping out the corner pieces is avoided. To this end, sheet gelatine is chosen as starting material, of which the corner as a whole is made, which can be made adhesive on all sides by moistening it and stands folding without breakage or a material of similar features. The material suitable for the purposes of this invention must not only have the feature of being without any adhesive capacity in the dry state, and of proving to be adhesive after moistening, but it must also have the necessary toughness to be folded and doubled without breakage of edges.

The corner work pockets or pieces, according to this invention, are stamped out of such material, which differs from the brittle gelatine glass paper ordinarily used for the purpose.

In the drawing, several constructional forms, by way of example are shown:

Figs. 14 and Figs. 6 and 7 show one constructional form, each with turn over folding. Figs. 8 and 9 show a constructional form with disconnected folding pieces, a base pasting piece, according to Fig. 10, being used as accessory. Fig. 5 shows the usual application of the corner pieces or pockets.

The shown forms of corner pockets are known per se. The difference, however, consists in the stamped out being made in all cases of a paperthin sheet adhesive in itself (as for inst. gelatine or the like), which needs no layer of pasting material and is folded without breakage on the edges. The corner pocket, the plan view of which is shown in Figs. 3 and 5 (on the left) is stamped out of a blank shown in Fig. 1, the triangular piece a being continuous with the side pieces a and a The lines of folding are indicated by dot and dash lines. After folding the pieces a and a which are overlapping on a more or in Germany December 30, 1930 less broad pasting edge, the corner, as seen from the back, appears as shown in Fig. 2. In Fig. 4, the folding of the comet-like corner is shown from its open side. By moistening the turned over border on the pieces a a and compressing them, the corner is finished and ready for use. (Fig. 3.) The corner produced in this way is made adhesive by moistening its back and is directly capable of being pasted on the base, the album sheet or the like (Fig. 5).

As shown in Figs. 6 and 7, the corner piece is formed of a blank somewhat different from the blank shown in Fig. 1. In this case, the narrow folding edge b is folded to overlap the joining piece b behind the triangular piece 2). Preliminary to the folding of the blank, the edge 2) is moistened to adhere to the piece 12 when the folding is completed to form the corner pocket. When the back I) is moistened the corner will readily adhere to the base sheet.

In Figs. 8 and 9, a corner is shown, in which the pieces c c are laterally folded but do not overlap and join at their edges in the diagonal line if in the centre of the corner, the projecting edges leaving a wedge shaped gap e between them. This form of corner, in folding the same, requires no preliminary pasting and is a finished product and can be used immediately by moistening its back to render it adhesive. The gap e, in this form ready for use, facilitates the insertion of the card 85 corner.

These corners or pockets are preferably made of transparent gelatine sheet that may be rendered adhesive by moistening. They may also be coloured to suit the requirements. Referring to Figs. 8 and 9, a wafer like patch I, as shown in Fig. 10, consisting of coloured gelatine sheet, can be applied to the parts 0 0 As the two surfaces of the patch are adhesive when moistened, the 95 closing of the joining pieces 0 c by means of such a patch can be easily accomplished and the pocket can be easily applied to the album sheet (Fig. 5 on the right). By this means, a smooth guiding surface is provided at the gap e to facilitate the 109 insertion and fastening of the card corner.

The direct adhesive quality of the material capacity, as shown in the examples described, facilitates the manufacture of the comers from the stamped pieces ready for use, which can be supplied ready for use, only requiring moistening so that they can be instantly applied. The chief advantage is therefore the cheap manufacture of such comers by stamping and folding, without the special equipment necessary for laying on the no adhesive material.

The closing of the comers in form of comets can subsequently be done by hand or mechanically by means of simple moistening devices.

A subsequent decoration of the new comers, which consists either of transparent or coloured gelatine material, can be done by powdering the surfaces made somewhat adhesive, with bronze powder, brass foil or the like.

What I claim is:-

1. A mounting for securing the corner of a card on a leaf of an album comprising a sheet of thin gelatinous material, said sheet being folded into triangular form with overlapping portions secured together by moistening the overlapped portion, and the leaf being moistened upon that part of the sheet placed upon the leaf.

2. A mounting for securing the corner of cards to a leaf comprising a sheet formed from the material which when moistened will adhere to the sheet, said sheet being bent into triangular form to form a pocket for receiving the corners .of the card.

3. A mounting for securing corners of cards, photographs and similar articles to leaves of books, albums and the like, having the shape of triangular pockets and formed from blanks of a thin transparent material, such as gelatinous matter affording the property to become adhesive by moistening at any part of its surface, each pocket utilizable in combination with an additional triangular piece stamped but from differently coloured material of similar properties and adapted to form an underlying seal, both sides of which can be made adhesive by moistening.
